Using the ServerGuide Setup and Installation CD

The ServerGuide Setup and Installation CD includes an easy-to-use setup and installation program that is designed for your IBM server. The ServerGuide program detects the server model and hardware options that are installed and uses that information during setup to configure the hardware. The ServerGuide program simplifies operating-system installations by providing updated device drivers and, in some cases, installing them automatically.

To purchase the latest ServerGuide Setup and Installation CD, see the “ServerGuideUpdates” flyer that comes with your server library, or go to the ServerGuide fulfillment Web site at http://www.ibm.com/pc/coupon/.

The ServerGuide program has the following features to make setup easier:

v An easy-to-use interface with online help v Diskette-free setup, and configuration programs that are based on detected

hardware

v ServeRAID Manager program, which configures your ServeRAID adapter or

integrated SCSI controller with RAID capabilities if installed

v A system BIOS update program, which updates the BIOS code directly from the

v Device drivers that are provided for your server model and detected hardware v Operating-system partition size and file-system type that are selectable during

setup

ServerGuide features

Features and functions can vary slightly with different versions of the ServerGuide program. To learn more about the version that you have, start the ServerGuide Setup and Installation CD and view the online overview. Not all features are supported on all server models.

The ServerGuide program requires a supported IBM server with an enabled startable (bootable) CD-ROM drive. In addition to the ServerGuide Setup and Installation CD, you must have your operating-system CD to install your operating system.

The ServerGuide program has the following features:

v Sets system date and time. v If installed, detects the SCSI RAID adapter, controller, or integrated SCSI

controller with RAID capabilities and runs the SCSI RAID configuration program.

v Updates the licensed internal code (firmware) level without diskettes. v Checks the system BIOS code and microcode (firmware) levels of supported

options to determine whether a later level is available from the CD. You can perform updates without using diskettes.

v Creates a System Partition on the default drive. You can run server-specific utility

programs after setup.

v Detects installed hardware options and provides updated device drivers for most

adapters and devices.

v Creates a setup-replication diskette for replicating setup selections for other

servers of the same model.

v Provides diskette-free installation for supported operating systems. v Provides a replicated installation path for multiple installations of supported

operating systems.

Chapter 2. Configuring your server 11

v Includes an online README file with links to tips for your hardware and

operating-system installation.

Setup and configuration overview

When you use the ServerGuide Setup and Installation CD, you do not need setup diskettes. You can use the CD to configure any supported IBM server model. The ServerGuide program checks your system BIOS, service processors, and other system hardware to determine if system updates are available. The setup program provides a list of tasks that are required to set up your server model. On a server with a ServeRAID adapter or integrated SCSI controller with RAID capabilities, you can run the SCSI RAID configuration program to create logical drives.

Note: Features and functions can vary slightly with different versions of the

ServerGuide program.

When you start the ServerGuide Setup and Installation CD, the program performs the following tasks:

v The ServerGuide program prompts you for your language, country, and keyboard

layout. (This information is stored and later passed to the operating-system installation program.)

v The ServerGuide program displays choices for running the configuration

programs. For example: – The Express Configuration method runs the required programs for your

server, based on the hardware that is detected.

– The Custom Configuration method displays all programs that are available for

your server, and you decide which programs to run.

– The Replicated Configuration method provides the option of duplicating your

setup selections to other servers that are the same model.

v If you select the Custom Configuration method, the following features are

optional. If you select the Express Configuration method, some or all of these features are run, depending on the hardware that is detected:

– The Set Date and Time feature is provided so that you do not have to use the

Configuration/Setup Utility program to access these settings.

– The Clear Hard Disks feature is provided so you can delete all partitions on all

hard disk drives.

– The ServerGuide program checks the server BIOS code and microcode

(firmware) levels for supported options and then checks the CD for a newer level. The CD content might be newer than the BIOS code and firmware level. The ServerGuide program can perform a flash update of the BIOS code and supported microcode (firmware) options without using diskettes.

– The SCSI RAID configuration program starts, leading you through the entire

configuration process.

– The ServerGuide program creates a System Partition on the default drive.

v The ServerGuide program displays a confirmation summary, so that you will

know when you have completed all the required tasks. Then, you are ready to install your operating system.

Notes:

1. Plug and Play adapters are configured automatically. Non-Plug and Play adapters or non-IBM adapters might require switch settings, additional device drivers, and installation after the operating system is installed. See the documentation that comes with the adapter.

12 xSeries 305 Type 8673: Hardware Maintenance Manual and Troubleshooting Guide

2. Diagnostics for your server come in BIOS code or on a separate diagnostics CD.

System Partition

The ServerGuide program creates a 50 MB System Partition on the default drive. The System Partition contains server-specific utility programs such as service-processor disk operating system (DOS) utilities, system diagnostics, flash BIOS updates, and other programs. Programs in the System Partition vary by server model, and not all server models run utility programs from the System Partition. To determine which ones do, start the ServerGuide Setup and Installation CD and view the online overview.

After setup is complete, you can access programs in the System Partition by restarting the server and pressing Alt+F1 when the prompt is displayed. The System Partition menu displays the programs that are available on your server model.

Typical operating-system installation

You can use the ServerGuide program to shorten your installation time. The ServerGuide program provides the device drivers that are required for your hardware and for the operating system that you are installing. This section describes a typical ServerGuide operating-system installation.

Note: Features and functions can vary slightly with different versions of the

ServerGuide program.

1. After you have completed the setup process, the operating-system installation program starts. (You will need your operating-system CD to complete the installation.)

2. The ServerGuide program stores information about the server model, service processor, hard disk drive controllers, and network adapters. Then, the program checks the CD for newer device drivers. This information is stored and then passed to the operating-system installation program.

3. With some operating-system installations, you can create an operating-system replication diskette for setting up additional servers. This diskette contains the Internet protocol (IP) address, server name, and other selections.

4. The ServerGuide program presents operating-system partition options that are based on your operating-system selection and the installed hard disk drives.

5. If you are installing the operating system from diskettes, the ServerGuide program lists the diskettes that you must create and the optional device-driver diskettes (for installed adapters or controllers) that you might want to create.

6. The ServerGuide program prompts you to insert your operating-system CD and restart the server. At this point, the installation program for the operating system takes control to complete the installation.

Setting up or updating multiple servers

You can use the ServerGuide program to create diskettes that help you set up or update multiple servers. You can modify information on the diskettes as you use them to set up or update other servers.

Note: Availability and function can vary by server model and by the hardware that

is installed.

Chapter 2. Configuring your server 13

You can create a setup-replication diskette, which contains your hardware configuration selections. Use this diskette to replicate selections to other servers that are of the same model.

Configuring the Gigabit Ethernet controller

Your server comes with two integrated Gigabit Ethernet controllers. The controllers provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps local area network (LAN) and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network.

When you connect the server to a network, the Ethernet controllers detect the data-transfer rate (10 Mbps, 100 Mbps, or 1 Gbps) of the network and automatically operates at that rate. If the Ethernet ports that your server is connected to auto-negotiation, the controllers automatically operate in standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex (HDX), or full duplex (FDX) mode. The controllers supports 1 GB speeds.

High-performance Ethernet options

The Ethernet controllers support teaming options, virtual LANs, and priority packets, which improve performance, security, and throughput. These options are supported by the integrated Ethernet controller and by adapters such as the IBM 10/100/1000 Ethernet Adapter and the IBM 10/100/1000 EtherJet PCI family of adapters.

Teaming options

The Ethernet controller supports teaming options. A team consists of two or more integrated Ethernet controllers, two or more Ethernet adapters, or a combination of

Chapter 2. Configuring your server 15

Ethernet controllers and adapters. Teaming options improve throughput and fault tolerance on a server running Microsoft Windows 2000, Windows NT 4.0, Linux, or Novell NetWare 4.1x or later. The controller supports the following teaming options:

v Adapter fault tolerance (AFT) provides automatic redundancy for Ethernet

controllers. It supports from two to four controllers per team. You can configure one of the integrated Ethernet controllers or adapters as the primary controller. If the primary connection fails, the secondary controller takes over. When the primary connection is restored, network traffic returns to the primary controller.

v Adaptive load balancing (ALB) balances data transmission among two to four

controllers. ALB includes AFT. You can use ALB with any 100BASETX/1000BASE-T switch.

v Cisco Fast EtherChannel (FEC) improves transmission and reception

throughput among two to four controllers. FEC includes AFT. You can use FEC only with a switch that has FEC capability.

Chapter 3. Diagnostics

This section provides basic troubleshooting information to help you resolve some common problems that might occur with your server.

If you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance” on page 85 for more information.

General checkout

The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD. These programs provide the primary methods of testing the major components of the server.

If you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

A failed system might be part of a shared hard disk drive cluster (two or more systems sharing one or more external storage devices). Before you run diagnostics, verify that the failing system is not part of a shared hard disk drive cluster.

A system might be part of a cluster if:

v The system is identified as part of a cluster. v One or more external storage units are attached to the system and at least one

of the attached storage units is also attached to another system or unidentifiable source.

v One or more systems are located near the failing system.

If the failing system is suspected to be part of a shared hard disk drive cluster, you can run all diagnostic tests except the diagnostic tests that test the storage unit (hard disk drive residing in the storage unit) or the storage adapter attached to the storage unit.

Notes:

1. For systems that are part of a shared hard disk drive cluster, run one test at a time in looped mode. Do not run all tests in looped mode, because this could enable the hard disk drive diagnostic tests.

2. If multiple error codes are displayed, diagnose the first error code that is displayed.

3. If the computer stops with a POST error, go to “POST error codes” on page 69.

4. If the computer stops and no error is displayed, go to “Undetermined problems”

on page 77.

5. For power supply problems, see “Power checkout” on page 26.

6. For safety information, see “Safety information” on page 87.

7. For intermittent problems, check the error log.

Small computer system interface messages

If you receive a SCSI error message, see “Diagnostic error codes” on page 65.

Note: If your server does not have a hard disk drive, ignore any message that

indicates that the BIOS is not installed.

Diagnostic programs and error messages

The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD. These programs are the primary method of testing the major components of your server.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when the diagnostic programs are run.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where: fff is the three-digit function code that indicates the function being

tested when the error occurred. For example, function code 089 is for the microprocessor.

ttt is the three-digit failure code that indicates the exact test failure that

was encountered. (These codes are for trained service personnel; see “Diagnostic error codes” on page 65).

iii is the three-digit device ID. (These codes are for trained service

personnel; see “Diagnostic error codes” on page 65).

date is the date that the diagnostic test was run and the error recorded. cc is the check value that is used to verify the validity of the

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition.

A general procedure for troubleshooting power problems is as follows:

1. Turn off the server and disconnect all ac power cords.

2. Check for loose cables in the power subsystem. Also check for short circuits, for example, if there is a loose screw causing a short circuit on a circuit board.

3. Remove adapters and disconnect the cables and power connectors to all internal and external devices until the server is at the minimum configuration required to start the server (see “Minimum operating requirements” on page 77).

26 xSeries 305 Type 8673: Hardware Maintenance Manual and Troubleshooting Guide

4. Reconnect all ac power cords and turn on the server. If the server starts up successfully, replace adapters and devices one at a time until the problem is isolated. If the server does not start up from the minimal configuration, replace FRUs of minimal configuration one at a time until the problem is isolated.

To use this method, it is important to know the minimum configuration required for a system to start (see page 77).

Troubleshooting the Ethernet controller

This section provides troubleshooting information for problems that might occur with the 10/100/1000 Mbps Ethernet controller.

Network connection problems

If the Ethernet controller cannot connect to the network, check the following conditions: v Make sure that the cable is installed correctly.

The network cable must be securely attached at all connections. If the cable is attached but the problem remains, try a different cable.

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps, you must use Category 5 or higher cabling.

v Determine whether the hub supports auto-negotiation. If it does not, try

configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.

v Check the Ethernet controller LEDs on the operator information panel and on the

rear of the server. These LEDs indicate whether a problem exists with the connector, cable, or hub.

– The Ethernet transmit/receive activity LED, on the operator information panel,

is lit when the Ethernet controller sends or receives data over the Ethernet Network. If the Ethernet transmit/receive activity LED is off, make sure that the hub and network are operating and that the correct device drivers are installed.

– The Ethernet link status LED, on the rear of the server, is lit when the

Ethernet controller receives a LINK pulse from the hub. If the LED is off, there might be a defective connector or cable or a problem with the hub.

v Make sure that you are using the correct device drivers which are supplied with

your server.

v Check for operating-system-specific causes for the problem. v Make sure that the device drivers on the client and server are using the same

protocol.

v Test the Ethernet controller.

The way the Ethernet controller is tested depends on which operating system you are using (see the Ethernet controller device driver README files).

Ethernet controller troubleshooting chart

Use the following troubleshooting chart to find solutions to 10/100/1000 Mbps Ethernet controller problems that have definite symptoms.

Ethernet link status LED does not work.

The Ethernet transmit/receive activity LED does not work.

Data is incorrect or sporadic.

The Ethernet controller stopped working when another adapter was added to the server.

The Ethernet controller stopped working without apparent cause.

FRU/actions

The PCI BIOS interrupt settings are incorrect.

Check the following: v Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also

assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function well

when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet controller or the other device. For example, for NetWare Versions 3 and 4, it is recommended that disk controllers not share interrupts with LAN controllers.

v Make sure that you are using the most recent device driver available from the World

Wide Web.

v Reseat or replace the adapter. Check the following:

v Make sure that the hub is turned on. v Check all connections at the Ethernet controller and the hub. v Use another port on the hub. v If the hub does not support auto-negotiation, manually configure the Ethernet controller

to match the hub.

v If you manually configured the Duplex mode, make sure that you also manually

configure the speed.

v Reseat or replace the adapter. Check the following:

v Make sure that you have loaded the network device drivers. v The network might be idle. Try sending data from this server.

Check the following: v Make sure that you are using Category 5 or higher cabling when operating the server at

100 Mbps or at 1000 Mbps.

v Make sure that the cables do not run close to noise-inducing sources like fluorescent

lights.

Check the following:

v Make sure that the cable is connected to the Ethernet controller. v Make sure that your PCI system BIOS code is current. v Reseat the adapter. v Determine if the interrupt (IRQ) setting assigned to the Ethernet adapter is also assigned

to another device in the system. Use the Configuration/Setup Utility program to determine if this is the case.

Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet adapter or the other device.

v Reseat or replace the adapter. Check the following:

v Try a different connector on the hub. v Reinstall the device drivers. See your operating-system documentation and the

ServerGuide information.

v Reseat or replace the adapter.

Chapter 4. Customer replaceable units

This chapter provides instructions for adding options to your server. Some option-removal instructions are provided in case you need to remove one option to install another.

Installation guidelines

Before you begin installing options in your server, read the following information: v Read “Handling static-sensitive devices”and “Safety information” on

page 87.“Handling static-sensitive devices”. This information will help you work safely with your server and options.

v Make sure that you have an adequate number of properly grounded electrical

outlets for your server, monitor, and other devices that you will connect to the server.

v Back up all important data before you make changes to disk drives. v Have a small Phillips screwdriver available. v For a list of supported options for your server, go to

http://www.ibm.com/pc/compat/ on the World Wide Web.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that:

v Each of the drive bays has a drive or a filler panel. v Space is available around the server to allow the server cooling system to work

properly. Refer to the documentation that comes with the rack.

v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan as soon as possible.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices, including your server.

To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted

metal part of the server for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, place it back into its static-protective package. Do not place the device on your server cover or on a metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

indoor humidity and increases static electricity.

Gigabit Ethernet port

Your server comes with two integrated Gigabit Ethernet controllers. These controllers provide an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

To access the Ethernet port, connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of your server.

Note: The 100BASE-TX/1000BASE-T Fast Ethernet standard requires that the

cabling in the network be Category 5 or higher.

The Ethernet (RJ-45) connector has two LEDs. The Ethernet link LED is on the right. When this green LED is on, there is an active connection on the Ethernet port. The Ethernet activity LED is on the left. When this green LED is on, there is activity between the server and the network. These LEDs have the same functions as the Ethernet link LED and the Ethernet activity LED on the rear of the server (see the User’s Guide on the IBM xSeries Documentation CD for information about the Configuration/Setup Utility program).

Configuring the Gigabit Ethernet controller

The Ethernet controllers are integrated on the system board. These controllers provide an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks

Chapter 4. Customer replaceable units 47

and provides full duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). You do not need to set any jumpers or configure the controllers for your operating system before you use the Ethernet controllers. However, you must install a device driver to enable your operating system to address the Ethernet controllers. The device drivers are provided on the ServerGuide Setup and Installation CD.

When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps, 100 Mbps, or 1000 Mbps) on the network and then sets the controllers to operate at the appropriate rate. In addition, if the Ethernet ports that your server is connected to support auto-negotiation, the Gigabit Ethernet controllers will set the appropriate duplex state. That is, the Ethernet controllers will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex (HDX), or full duplex (FDX). The controllers supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

For information on configuring your Ethernet controller, see the Broadcom NetXtreme Gigabit Ethernet Software CD that comes with your server. For updated information about configuring your Ethernet controllers, go to the IBM Support Web site at http://www.ibm.com/pc/support and navigate to the area for your specific server type. From this area you can download documentation, the most current device drivers for your server, and software that supports advanced networking functions. After downloading, run the downloaded program launch.exe.

High-performance Ethernet modes

Your Ethernet controllers support optional modes, such as teaming, priority packets, load balancing, fault tolerance, and virtual LANs, which provide higher performance, security, and throughput for your server. These modes apply to the integrated Ethernet controller and to the controllers on supported Ethernet adapters.

Chapter 6. Symptom-to-FRU index

This index supports xSeries 305 servers.

Notes:

1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms.

2. For IBM devices not supported by this index, refer to the manual for that device.

3. Always start with “General checkout” on page 17.

The symptom-to-FRU index lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this symptom-to-FRU index to help you decide which FRUs to have available when servicing the computer.

The first column of the two-column tables in this index lists error codes or messages, and the second column lists one or more suggested actions or FRUs to replace. Take the action (or replace the FRU) suggested first in the list of the second column, then try the server again to see if the problem has been corrected.

Note: Try reseating a suspected component or reconnecting a cable before

replacing the component.

The POST BIOS code displays POST error codes and messages on the screen.

POST (ISPR) error procedures

Use the ISPR error procedures to help you solve ServeRAID problems. A complete list of error codes is listed at “ServeRAID error codes” on page 75.

Note: Where the ISPR Error Procedures refer to a Hard disk drive backplane, see

the chapter of this publication that concerns service replaceable units.

EF10 (Default ISPR)

1. No ISPR error present.

9ZXX thru BZXX (SCSI bus error caused either by cables, termination, defective drives, etc.)

1. Isolate between SCSI subsystem and controller by disconnecting all hard disk drive cables from suspect card, and reboot.

Chapter 6. Symptom-to-FRU index 73

CAUTION: Do not press F5. Doing so changes the server’s configuration.

If an ISPR error is still present, perform the following actions until the error is no longer present:

a. Reseat the controller b. Replace the controller

Notes:

a. SCSI channel cable details, if any, appear elsewhere in this publication. b. The adapter/controller detects a configuration change. Do not choose Save

Changes. Instead, press F10 to bypass any options to this effect.

2. If ISPR error is EF10 after disconnecting cables:

a. Identify which channel is causing the error by the second digit (Z) of the

original ISPR code as indicated in the following table:

Note: ServeRAID-4H controllers have 4 channels; ServeRAID-4L and -4Lx

controllers have only one channel; and ServeRAID-4M and -4Mx controllers have 2 channels. ServeRAID-5i controllers have no channels. The ServeRAID-5i uses the channel connectors of the server’s onboard integrated SCSI controller.

86 xSeries 305 Type 8673: Hardware Maintenance Manual and Troubleshooting Guide

Appendix B. Related service information

Note: The service procedures are designed to help you isolate problems. They are

written with the assumption that you have model-specific training on all computers, or that are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after

maintenance.

v When lifting any heavy object:

1. Ensure you can stand safely without slipping.

2. Distribute the weight of the object equally between your feet.

3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any objects

that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

v Do not perform any action that causes hazards to the customer, or that makes

the equipment unsafe.

v Before you start the machine, ensure that other service representatives and the

customer’s personnel are not in a hazardous position.

v Place removed covers and other parts in a safe place, away from all personnel,

while you are servicing the machine.

v Keep your tool case away from walk areas so that other people will not trip over

it.

v Do not wear loose clothing that can be trapped in the moving parts of a machine.

Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

v Insert the ends of your necktie or scarf inside clothing or fasten it with a

nonconductive clip, approximately 8 centimeters (3 inches) from the end.

v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your

clothing. Remember: Metal objects are good electrical conductors.

v Wear safety glasses when you are: hammering, drilling soldering, cutting wire,

attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

v After service, reinstall all safety shields, guards, labels, and ground wires.

Replace any safety device that is worn or defective.

v Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION: Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the server covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have

handles covered with a soft material that does not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

v Find the room emergency power-off (EPO) switch, disconnecting switch, or

electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Disconnect all power before:

– Performing a mechanical inspection – Working near power supplies – Removing or installing main units

v Before you start to work on the machine, unplug the power cord. If you cannot

unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

v If you need to work on a machine that has exposed electrical circuits, observe

the following precautions: – Ensure that another person, familiar with the power-off controls, is near you.

Remember: Another person must be there to switch off the power, if necessary.

– Use only one hand when working with powered-on electrical equipment; keep

the other hand in your pocket or behind your back. Remember: There must be a complete circuit to cause electrical shock. By

observing the above rule, you may prevent a current from passing through your body.

– When using testers, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you

from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

88 xSeries 305 Type 8673: Hardware Maintenance Manual and Troubleshooting Guide

v Regularly inspect and maintain your electrical hand tools for safe operational

condition.

v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that

it has been powered-off.

v Always look carefully for possible hazards in your work area. Examples of these

hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

v Do not touch live electrical circuits with the reflective surface of a plastic dental

mirror. The surface is conductive; such touching can cause personal injury and machine damage.

v Do not service the following parts with the power on when they are removed from

their normal operating places in a machine: – Power supply units – Pumps – Blowers and fans – Motor generators

and similar units. (This practice ensures correct grounding of the units.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present: v Electrical hazards, especially primary power (primary voltage on the frame can

cause serious or fatal electrical shock).

v Explosive hazards, such as a damaged CRT face or bulging capacitor v Mechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).

2. Turn off the computer. Disconnect the power cord.

3. Check the power cord for:

Appendix B. Related service information 89

a. A third-wire ground connector in good condition. Use a meter to measure

third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

b. The power cord should be the appropriate type as specified in the parts

listings.

c. Insulation must not be frayed or worn.

4. Remove the cover.

5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the server, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.

2. Make sure that the ESD-protective devices you use have been certified (ISO

9000) as fully effective.

When handling ESD-sensitive parts:

v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap.

v Use the black side of a grounded work mat to provide a static-free work surface.

The mat is especially useful when handling ESD-sensitive devices.

v Select a grounding system, such as those in the following list, to provide

protection that meets the specific service requirement.

Note: The use of a grounding system is desirable but not required to protect

against ESD damage.

– Attach the ESD ground clip to any frame ground, ground braid, or green-wire

ground.

– Use an ESD common ground or reference point when working on a

double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

– Use the round ground-prong of the ac plug on ac-operated computers.
